Portland, ME population, income and ZIP codes

Portland city is a small city in Maine, with 68,505 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it first of 155 ranked by population. The median age here is 37.5 years against 39.1 nationally, a slightly younger profile than the country as a whole. At this size the Census also publishes one-year estimates; the five-year values used here are steadier and let you compare against smaller neighbours on the same basis.

Households in Portland city earn a median of $76,174 a year, 3% below the national figure of $78,538 and 29% above the $58,992 median for the 106 Maine cities we cover. Median household income counts every pre-tax dollar arriving at an address — wages, self-employment, Social Security, pensions, interest and public assistance — for everyone living there, so multi-earner households pull the figure up even where individual pay is modest. Poverty reaches 11.2% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Portland city is valued at $452,600, 49.2% above the national figure and 104% above the $221,600 peer median, while median gross rent runs $1,487 a month, 5.8% above the national figure, or roughly $17,844 across a full year. A household on the local median income would put about 23.4% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is within the standard affordability guideline. The home-price-to-income ratio works out to 5.9×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 46.7% of occupied homes are owner-occupied versus 65% nationally, so the market leans more heavily on renters. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.

All values below were released by the Census for this exact geography, with no gap-filling on our side. Small-area estimates still carry wider margins of error than state or national figures, so check the linked ACS tables before relying on them for lending, appraisal or legal work.
